Lead Application Security Engineer
We are seeking a Lead Application Security Engineer to drive the design, implementation and continuous improvement of secure software development practices across a diverse technology estate. This is a hands-on leadership role for an experienced security professional who can influence engineering teams, shape security strategy and embed effective controls throughout the software development lifecycle. You will work closely with developers, architects, platform teams and risk stakeholders to identify vulnerabilities early and support the delivery of resilient, secure applications.
Your responsibilities will include defining and maintaining application security standards, patterns and guidance; leading threat modelling, secure design reviews and architecture assessments; and overseeing security testing, including static and dynamic analysis, software composition analysis and penetration testing. You will triage and prioritise findings, provide practical remediation advice and track risks through to resolution. You will also help develop security tooling and automation within CI/CD pipelines, improve vulnerability management processes, and contribute to incident investigations where application security is a factor. An important part of the role will be mentoring engineers, promoting security awareness and establishing meaningful metrics to measure progress and risk reduction.
You will bring substantial experience in application or product security, with a strong understanding of secure coding principles, common web and API vulnerabilities, and recognised frameworks such as OWASP. Experience with cloud environments, modern development practices, DevSecOps tooling and infrastructure-as-code would be highly valuable. You should be confident reviewing code and designs, communicating complex risks to both technical and non-technical audiences, and influencing decisions without relying on formal authority. Relevant professional certifications or demonstrable equivalent experience are welcome. The successful candidate will be analytical, collaborative and pragmatic, with the leadership skills to build trusted relationships while maintaining high security standards.
